A. The new XP Welcome screen is actually as simple as it looks. When you first boot the machine, log off, or use Fast User Switching, the system displays a screen with the computer's local accounts. To log on as one of these accounts, click the appropriate user name or picture. If you have a password, the system will display an area for your password (if you don't need a password, you'll be logged on).
Type your password and click the right arrow or press Enter. If you forget your password and configured a password hint, you can click the question mark (?) next to the right arrow to display your hint. Note that these password hints aren't secure; anyone can see them by clicking the ?, so don't make them too obvious.
